1) To solve the first equation, we combine like terms and isolate y:
11 + 2.3y + 1.3y = 383.6y = 27y = 27 / 3.6y = 7.5
Therefore, the solution for y in the first equation is y = 7.5.
2) To solve the second equation, we first multiply both sides by 8 to get rid of the denominator:
8(2y - 1.8) / 8 = 0.7 * 82y - 1.8 = 5.6
Next, we isolate y by adding 1.8 to both sides:
2y = 5.6 + 1.82y = 7.4
Finally, we solve for y:
y = 7.4 / 2y = 3.7
Therefore, the solution for y in the second equation is y = 3.7.
1) To solve the first equation, we combine like terms and isolate y:
11 + 2.3y + 1.3y = 38
3.6y = 27
y = 27 / 3.6
y = 7.5
Therefore, the solution for y in the first equation is y = 7.5.
2) To solve the second equation, we first multiply both sides by 8 to get rid of the denominator:
8(2y - 1.8) / 8 = 0.7 * 8
2y - 1.8 = 5.6
Next, we isolate y by adding 1.8 to both sides:
2y = 5.6 + 1.8
2y = 7.4
Finally, we solve for y:
y = 7.4 / 2
y = 3.7
Therefore, the solution for y in the second equation is y = 3.7.
