6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
3x + 11 + 5x = 75 Collect 'like terms on the LHS 8x + 11 = 75 Subtract '11' from both sides 8x = 64 Divide both sides by '8' 8x/8 = 64/8 x = 8
8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
5x+3=8 is a simple equation, and I can tell you off the top of my head the answer is 1. Here's how to work it: 5x+3=8 5x+3(-3)=8(-3) 5x=5 5x(/5)=5(/5) x=1
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
4(8+2x)=5x+1132+8x=5x+118x-5×=11-323x=-213 3=-7Therefore the number is -7
3x + 11 + 5x = 75 Collect 'like terms on the LHS 8x + 11 = 75 Subtract '11' from both sides 8x = 64 Divide both sides by '8' 8x/8 = 64/8 x = 8
x in the equation equals 8 x=8 3*8+11+5*8=75
Assuming you meant y = 5X + 8, the slope is 5.
8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
