Express x in terms of y for the linear equation 2/3x + 4y = -7

ANSWER

EXPLANATION

We have

.

Expressing    in terms of   means we should rewrite the relation such that    will remain on one side of the equation while    and any other constant will be at the other side.

To make the subject, we add to both sides of the equation.

.

we now multiply the whole equation by the reciprocal of the coefficient of , which is .

This implies that;

This simplifies to;

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
