Can someone help me on this question of: 40 - 3 • x = 25 Please explain step by step to get marked

Hey there!

40 - 3 * x = 25

-3x + 40 = 25

ADD 40 to BOTH SIDES

-3x + 40 - 40 = 25 - 40

CANCEL out: 40 - 40 because it gives you 1

KEEP: 25 - 40 because it helps solve for the x-value

NEW EQUATION: -3x = 25 - 40

SIMPLIFY

25 - 40 = -15

NEW EQUATION: -3x = -15

DIVIDE -3 to BOTH SIDES

-3x/-3 = -15/-3

CANCEL out: -3/-3 because it gives you 1

KEEP: -15/-3 because it helps solve for the x-value

NEW EQUATION: x = -15/-3

SIMPLIFY

x = 5

Good luck on your assignment and enjoy your day!
