5X = 2X + 9 subtract 2X from each side 5X - 2X = 2X - 2X + 9 3X = 9 divide each sides integer by 3 (3/3)X = 9/3 X = 3 ------------check in original equation 5(3) = 2(3) + 9 15 = 6 + 9 15 = 15 checks out
yes and the answr is x = 9
The equation is 2(x) +3= 9. X would equal 3. The equation would now look like this, 2x3+3=9.
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
To put the equation 3y - 9 = 2x in y-intercept form (y = mx + b): 3y - 9 = 2x 3y = 2x + 9 (add 9 to both sides of the equation) y = 2/3 x + 3 (divide all terms by 3) The y-intercept is the b term in the equation, which in this example is 3.
