Someone plz answer i rlly need help Solve for a.<br><br> a+(−1.6)=−3.7
Norma-Jean [14]
Hi there!

All you need to do to solve for a is add 1.6 to both sides of the equation.

It will look like this:
a - 1.6 + 1.6 = -3.7 + 1.6

After this you will see that a = -2.1.

Hope this helps!
When in doubt just replace a with -2.1 and see if you still get -3.7. :)

Solve the system of equations by substitution
scoundrel [369]

Answer:

(x, y) = (1, 3)

Step-by-step explanation:

given the 2 equations

x + y = 4 → (1)

y = 3x → (2)

Substitute y = 3x into (1)

x + 3x = 4

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

y = 3 × 1 = 3

solution is (1, 3 )
