Solve the system of equations by substitution: y = x - 2

Mathematics
1 answer:
gizmo_the_mogwai [7]3 years ago
4 0

Step-by-step explanation:

y = x - 2

x + y = 12

Substitute the first expression for y into the second equation.

x + (x - 2) = 12

2x - 2 = 12

2x = 14

x = 7

Now plug into either equation to find y.

y = 7 - 2

y = 5

So the solution is (7, 5).

I need help please how do you solve 3( x - 1/3 ) = 52
Stels [109]
You would multiply 3 by whats in the parentheses and u would get 3x - 3 = 52. Then u would add 3 to both sides to get x by itself and then u would have 3x = 55. The divide both sides by 3 and then u would get x = 18.333333 or 18 and a third

Three complementary angles are in the ratio 1:2:3 what is the measurement of the smallest angle
Llana [10]

Answer: 30

Step-by-step explanation:

Let x stand for the measure of angle 1. Then. 2x for angle 2 and finally 3 x for angle 3.

So, x + 2x + 3x = 180

and 6x = 180

Therefore, x = 30, 2x = 60 and 3x = 90.
