2 separate equations. Find x and y.

Consider the following system of equations: 2x − 3y = 2, 4x + 2y = −1 −5x − 6y = d For what value of d does the above system have a solution? For this value of d, graph all...

Solve by elimination. Indicate if the system is inconsistent or has an infinite number of solutions. Leave your final answers in fractional form, do NOT use decimals. 5x + 2y − 2z = −1, 4x...

A merchant wants to mix pecans, which sell for $6 per pound, with cashews that sell for $12 per pound to make a 96-pound mixture he can export for $8 per pound. How many pounds of pecans and how many...

solve that system of linear equations using the elimination method

a year long study was done on the gases released by a power plant. A scientist measured the amount of two important gases. He found that here was 64 times as much sulfur dioxide as nitrogen dioxide...

A merchant wants to mix pecans, which sell for $3.00 per pound, with cashews that sell for $6.00 per pound to make a 48 pound mixture he can export for $4 per pound. How many pounds of pecans and...

5x-1 / 3 + y+7 / 4 = 11 x+1/2 - x-y/3=3 Find the solution set The 5x-1 is over 3, the y+7 is over 4 x+1 is over 2, x-y is over 3

Solve the system. State whether the system is inconsistent or has infinitely many solutions. If the system has infinitely many solutions, write the solution set with y arbitrary. 4...

in part of a fundraising campaign, logan organized a dog show. The cost to rent the park was $1300 plus $2.50 per person for the snack bar fee. logan charged $5 for each student ticket and $8 for...

this is algebra, and im working on solving by elimination

Solve the system. State whether the system is inconsistent or has infinitely many solutions. If the system has infinitely many solutions, write the solution set with y arbitrary. 2x+3y=5...

Macadamia nuts cost $16.50 per pound. Regular nuts cost $9.25 per pound. How many pounds of macadamia nuts and how many pounds of regular nuts should I combine to produce 40 pounds of a mixed nut...
