We need to add like terms and distribute before we try to isolate X. 10x+3=8x+4-2 10x+3=8x+2
Now let's isolate x. We should start with subtracting 8x from both sides. 2x+3=2 Now, let's subtract 3 from both sides. 2x=-1 Now divide each side by 2. X=-0.5 We now know x is -0.5, so let's check. 5(-0.5)+5(-0.5)+3=4[2(-0.5)+1]-2 -2.5-2.5+3=4(0)-2 -5+3=0-2 -2=-2
