7x=42 x=42/7 or, x=6
x=6
7x-3=39 7x=42 x=6
-7x - 3y = 42, let y = 0 and replace 0 for y into the equation -7x - 3(0) = 42 -7x = 42, divide by -7 to both sides x = -6 so the x-intercept is -6, or the x-intercept point is (-6, 0).
7x = 42 so x = 42/7 and therefore x = 6
7x=42 x=42/7 or, x=6
7x + 9 = 51 7x = 42 x = 42/7 = 6
-7x = -42 7x = 42 x = 6
x=6

7x-3=39 7x=42 x=6
31=7x-11, 31+11=7x, 42/7=x, x=6 :)

if the equation was 7x = 42. The answer would be x = 6
Let x be the varible: 7x-5 = 37 7x = 37+5 7x = 42 x = 6
