Answer:
2x+6y = 10
3x+9y = 15
Step-by-step explanation:
We can multiply the equation by 2
2( x + 3y )= 5*2
2x+6y = 10
Or we can multiply by 3
3( x + 3y) = 5*3
3x+9y = 15
Multiplying each side by the same number gives us an equivalent equation
Standard form is
Ax +By = C
Which the equation is already written in
Answer:
1) x = 19
2) x = 24 1/3
Step-by-step explanation:
1) there are 360 degrees in a 4-sided polygon
90 + 90 + 4x - 14 + 5x + 23 = 360
9x + 9 = 180
9x = 171
x = 19
2) there are 720 degrees in a 6-sided polygon
since this hexagon is 'regular' then all angles are equal and measure 120°
6x - 26 = 120
6x = 146
x = 24 1/3
