The 1st step is to include an equality sign and give the plus or minus values of 2y and 10 otherwise it can't be solved

-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
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.
Without any equality signs the given expression is not an equation and so therefore any solutions are not possible.
x=1, y=1
To convert the equation 8x - 5y = -40 into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, you need to solve for y. First, isolate y by subtracting 8x from both sides to get -5y = -8x - 40. Then, divide by -5 to get y = 8/5x + 8, which is the slope-intercept form of the equation. The slope is 8/5 and the y-intercept is 8.
