Answer: x=-4

Explanation: to find the X intercept you need to make y=0 which basically eliminates the 4y leaving you with 7x=-28 then you just divide both both sides by 7 which leaves you at x=-4

Answer x intercept is -4

Step by step

Substitute 0 for y and solve for x

7x + (4)(0) = -28

Divide both sides by 7 to solve for x

7/7 x = -28/7

x = -4
