X = 3
y = -1

get the x or y by itself first (second eq. is easier)
So, x + 2y = 1
-2y -2y
Now we get:
x = -2y +1 Plug it into the other equation.

2x + 3y = 3
2(-2y +1) + 3y = 3
-4y + 2 + 3y = 3
-1y +2 = 3
+1y -3 -3 +1 y

y = -1 (plug into either eq to get x)

<span>x + 2y = 1
</span>x+2(-1) = 1
x-2=1
+2 +2

x = 3

11.(A-CED.A.1 ) Write and solve the equation

Black_prince [1.1K]

Answer:

Ahmed runs 6 miles each day

Step-by-step explanation:

∵ Ahmad runs m miles each day

∵ Ali runs twice as many miles as Ahmad

→ That means Ali runs 2 × m miles each day

∴ Ali runs 2m miles each day

∵ Altogether, they run 18 miles each day

→ Add m and 2m, then equate the sum by 18

∴ m + 2m = 18

∴ 3m = 18

→ Divide both sides by 3 to find m

∵ $\frac{3m}{3}=\frac{18}{3}$

∴ m = 6

∵ m represents the number of miles that Ahmed runs each day

∴ Ahmed runs 6 miles each day
