7x + 9 = 51 7x = 42 x = 42/7 = 6
35
-7x = -42 7x = 42 x = 6
6 + 7x = -36 first, subtract 6 from both sides 7x = -42 then, divide both sides by 7 7x/7 = -42/7 x = -6 to check, put -6 back into the original equation: 6 + (7 x -6) = -36 6 - 42 = -36
6
7x=42 x=42/7 or, x=6
x=6
7x + 9 = 51 7x = 42 x = 42/7 = 6
35
7x = 42 so x = 42/7 and therefore x = 6
if the equation was 7x = 42. The answer would be x = 6
The answer to the equation 7 times 42 equals 294. This is taught in math.

The required equation is: -7x = 63
7x = 42 Divide both sides by '7'. Hence x = 42/7 x = 6 The answer!!!!!
-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).
