Answer:
x = -1, y = 1
Step-by-step explanation:
Multiply the top equation by 2:
Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:
Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.
Answer:
x = 4, -10 used math book
The expression 2y² - 2 + 4x - 2x + 3 - 2x + 5y² solved by collecting like terms is 7y² + 2x + 1

Check the picture below.
now, based on the provided information, we know the hexagon and triangle are regular polygons, <u>equal sides and equal angles</u>, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.
now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.
if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a <u>full revolution</u> will be 360°, so the remaining angle in green there must be 360° - 120° - 136° = 104°, and her twin at vertex J is also 104°.
