It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus

(2a^2b^2)^3(-7a^13b^2)

a^2b^2c^2 ^2 is squared

2 [x - B] = 5B + 3Perform the indicated multiplication on the left side:2x - 2B = 5B + 3Add 2B to each side of the equation:2x = 7B + 3Divide each side by 2 :x = 7/2 B + 3/2

Your two equations are: AX + BY = A - B BX - AY = A + B + B Because you have four variables (A, B, X, Y), you cannot solve for numerical values for X and Y. There are a total of four answers to this question, solving each equation for X and Y independently. First equation: X = (A - B - BY)/A Y= (A - B - AX)/B Second equation: X = (A +2B +AY)/B Y = (BX - A - 2B)/A
