3x - 2 + x = 42
3x + x - 2 = 42 (add alike terms)
4x - 2 + 2 = 42 + 2 (in order to leave the term with tha variable alone, we add 2 to both sides)
4x = 44
4x/4 = 44/4 (divide by 4 to both sides to leave the variable alone)
x = 11
Thus, for x = 11 the given equation is true.
3x + 2 = 3x + 6 This is not possible.
(2, -1)
Their graphs are.
3x + 2 = 0 3x = -2 x = -2/3
4x plus 7 plus 3x equals 19 plus xx = 2
3x + 2 = 3x + 6 This is not possible.
y=-2/3x with any y-intercept except -2.
(2, -1)
Their graphs are.
3x + 2 = 0 3x = -2 x = -2/3
4x plus 7 plus 3x equals 19 plus xx = 2
3x + 2 = -10 3x = -12 x = -4
x = 7 and 2/3
3x + 2 = Y
(-2, 4)
x + 2 = 3x-1 -2x = -3x = 1,5
x = 2
