7a - 2b = 5a + b a = 2b
a = 3b
a = a equals StartFraction 3 Over 2 EndFraction b. b
a = a equals StartFraction 2 Over 3 EndFraction b. b

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
