The ordered pair (1, -7) is a solution of the equation y = -7x + 2.
–4 = g + 1
To solve the equation -4 = g + 1, we can isolate the variable g by subtracting 1 from both sides:
-4 - 1 = g + 1 - 1
-5 = g
Therefore, g = -5.
w – 2 = –3
To solve the equation w - 2 = -3, we can isolate the variable w by adding 2 to both sides:
w - 2 + 2 = -3 + 2
w = -1
Therefore, w = -1.
6.4 = 4x
To solve the equation 6.4 = 4x, we need to isolate the variable x. We can do this by dividing both sides of the equation by 4:
6.4/4 = 4x/4
1.6 = x
Therefore, x = 1.6.
