If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
5x - 16 = 3x2x - 16 = 02x = 16x = 8
3x - 8 = 5x + 2 <+8 and - 5x off each side> -2x = 10 <divide each side by -2x> x = -5
Do you want the solutions to the equations? If so then: x = 7 and y = 4
5x=11y
3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
5x - 7 = 23 .....+7....+7 5x=30 --- --- 5.....5 --->(x=6)<---
x=0
When x equals 8, the value of 5x would be 5 times 8, which is 40.
7x-5x=8 2x=8 x=4
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
5x-4y=8
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
8x - y = 31 <=> y = 8x - 31. 5x + 3y = 23 => 5x + 3 * (8x - 31) = 23 <=> 5x + 24x - 93 = 23 <=> 29x = 23 + 93 <=> 29x = 116 <=> 29x/29 = 116/29 <=> x = 4. y = 8x - 31 => y = 8 * 4 - 31 <=> y = 32 - 31 <=> y = 1.
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
It is: y = -5x+8
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
