x=60 because if you add 5 to both sides then x/3=20, and then if you multiply both sides by three, x=60

∙ 14y ago5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
15 + n = 24 (subtract 15 from both sides) n = 9
subtract 15 from both sides then divide both sides by -4. g=12
45 = 30 + m Subtract 30 from both sides: 15 = m
30 divided by 2 equals 15 :)
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
15+b = 23 Subtract 15 from both sides b = 8
15 + n = 24 (subtract 15 from both sides) n = 9
subtract 15 from both sides then divide both sides by -4. g=12
45 = 30 + m Subtract 30 from both sides: 15 = m
30 divided by 2 equals 15 :)
The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.
15
To solve this, isolate x. first, add 10 to both sides. this will leave you with 2a + 15 = a Then, subtract 2a from both sides. This will leave you with 15 = -a Therefore, -15 = a
3x-5y=15 The equation-5y=15-3x Subtract 3x from both sidesy=-3+.6x Divide both sides by -5
You cannot solve it with two unknown values 'x' & 'y' . However, it can be rearranged to form a strasight line eq'n. Hence -3x -3y = -15 Cancel down by '3' Hence -x -y = -5 Multiply by '-1', Hence x + y = 5 Hence y = -x + 5 Is the straight line eq'n. It has a slope/gradient of '-1' ; the coefficient of 'x' It intercepts the y-axis at '5'. ; ( 0,5)
