2x-7=8. find the value of x​

The answer is X=15/2

Move all terms that don't contain
x to the right side and solve.
So you would first Add 7 to both sides. 2x=8+7
Then simply 8+7 to 15 so 2x=15
Then Divide both sides by 2
To get x=15/2
Hope that helps

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
