7q+12r=3q-4r
write a formula for g(q) in terms of q.

Step-by-step explanation:

Simplifying

-7q + 12r = 3q + -4r

Solving

-7q + 12r = 3q + -4r

Solving for variable 'q'.

Move all terms containing q to the left, all other terms to the right.

Add '-3q' to each side of the equation.

-7q + -3q + 12r = 3q + -3q + -4r

Combine like terms: -7q + -3q = -10q

-10q + 12r = 3q + -3q + -4r

Combine like terms: 3q + -3q = 0

-10q + 12r = 0 + -4r

-10q + 12r = -4r

Add '-12r' to each side of the equation.

-10q + 12r + -12r = -4r + -12r

Combine like terms: 12r + -12r = 0

-10q + 0 = -4r + -12r

-10q = -4r + -12r

Combine like terms: -4r + -12r = -16r

-10q = -16r

Divide each side by '-10'.

q = 1.6r

Simplifying

q = 1.6r

the answer is 45 i just did it on oddesy ware

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
