Y=4,200x +1400 solve for x

(y-1400)/4200 = x

Step-by-step explanation:

y=4,200x +1400

Subtract 1400 from each side

y-1400=4,200x +1400-1400

y - 1400 = 4200x

Divide each side by 4200

(y-1400)/4200 = 4200x/4200

(y-1400)/4200 = x

Steps to solve:

y = 4,200x + 1,400

~Subtract 4,200 to both sides

y - 4,200x = 4,200x - 4,200 + 1,400

~Simplify

y - 4,200x = 1,400

~Subtract y to both sides

y - y - 4,200x = 1,400 - y

~Simplify

-4,200x = 1,400 - y

~Divide -4,200 to both sides

-4,200x/-4,200 = 1,400-y/-4,200

~Simplify

x = 1,400-y/-4,200
