10 + y = 4y = 4 - 10 y = -6
15-y/4>10 15-10>y/4 [add y/4-10 to both sides] 5>y/4 [simplify lhs] 20>y [multiply by 4] y<20 [move y to lhs]
If you mean y+10 = 4 then the value of y is -6
If 4*y + 10 = 22Then 4*y = 12 (because 22 -10 = 12)Then y = 3 (because 4*3 =12)
4:6=10:y 4/6 =10/y 4×y = 6×10 4y/4 = 60/4 y =GH¢ 15 10 books cost GH¢15.00

14
y/4 = 10/8 Multiply both sides by 4:- y = 40/8 y = 5
X - Y = 10 X + Y = 4 -------------------+ ( add them ) 2X = 14 X = 7 ----------find Y in one of the equations; top looks good 7 - Y = 10 - Y = 3 Y = - 3 ---------------check both equations for consistency 7 - (- 3) = 10 7 + 3 = 10 10 = 10 ------------checks in top 7 + (- 3) = 4 7 - 3 = 4 4 = 4 ------------checks and is consistent (7, - 3) ( the answer )
If you mean: y = 4x+10 then the y intercept is 10 and the slope of the line is 4
y = 14
