-4(1-t) + 7t Multiply/Factor out -4 into whats in the parenthesis -4(1-t) ---> (-4) x (1) (-4) x (-t) Multiply (-4) x (1) ---> -4 (-4) x (-t) ---> 4t (negative times a negative is a positive) So now your problem reads -4 +...
Substitute the variables for the given numbers into the equation 3xy+2x x=2 y=3 ---> 3(2)(3) + 2(2) Use PEMDAS to solve. Multiply first 3(2)(3) + 2(2) ---> 18 +4 Then Add. Solve. 18 +4 ---> 22
To answer this problem the variable x has to be included in the problem. Ex. 8x-3=93 or 3x-8=28
