Question

Solve the equation for y. 7x - 3y = 4

Answer 1

nothing else provided?

Answer 2

if so, all you can do iss 'rearrange' for y...

Answer 3

Use substitution.

Answer 4

7(0) - 3y = 4

Answer 5

7x - 3(0) = 4

Answer 6

Then solve. fractions are not forbidden

Answer 7

it wants me to figure out what y is but i don't know how to solve it...answer is either y = x- or y = x+

Answer 8

Okay then.
7(0) - 3y = 4
-3y = 4
y = 4/-3

Answer 9

7x - 4/-3 = 4
7x = 16/3
Divide both by 7
x = 16/3 *1/7 = 16/21
So x = 16/21 and y = 4/-3
