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

=2b
a-2b is a binomial. It has two terms: a, and -2b.
a + 2b = c a = c - 2b
2B 2B or not 2B, that is the question.
-b+5b-2b=2b
