<span>6.4u−5.1u=−3.25

Simplify
1.3u = -3.25

Divide both sides by 1.3
1.3u/1.3 = -3.25/1.3

Simplify
u = -2.5</span>

HELP IM IN DESPERATE NEED!!!<br> What is the solution to this system of equations?

Paladinen [302]

[Given]

{ x + y = 6

{ x = y + 4

[Plug-in our x value & solve]

[Given] x + y = 6

[ Plug-in] (y + 4) + y = 6

[Distribute] y + 4 + y = 6

[Combine like terms] 2y + 4 = 6

[Subtract 4 from both sides] 2y = 2

[Divide both sides by 2] y = 1

[Answer]

Third option - (5, 1)

-> You do not need to solve for x since this is the only option that has y = 1, but to solve for x we would do y + 4 = 1 + 4 = 5, so this answer fully checks correctly

Have a nice day!
