We want to find x in times of y and z, so we want to have only 1 x on the LHS of equation, so 3x-7y=z /+7z (add 7z both sides) 3x=z+7z /:3 (divide 3 both sides) x = 3 z + 7 y - its the result.
x=7/3y+1/3z , answer
To solve for x in the equation 3 x − 7 y = z , we first add 7 y to both sides to get 3 x = z + 7 y . Then, we divide by 3 to isolate x , resulting in x = 3 z + 7 y .
