Answer:
13 = 3× +4 ; × = 3
18 = 16y² + 4y - 54 ; y = 2
-4 = 12b - 16 ; b = 1
24 = 14w + 10 ; w = 1
4 = 2x² - 5x +6 ; x = 2
?? = 8a² - 9a + 10 ; a = 3
6 = 16g - 42 ; g = 3
Step-by-step explanation:
1. Substitute × = 3 into 3×4:
3×3+4
9+4
=13
2. 16 × 2² + 4×2 - 54
16 × 4 + 4 × 2 - 54
64 + 4×2 - 54
64 + 8 - 54
72 - 54
=18
3. Substitute b = 1 into 12b 16:
12 - 16
=-4
4. Substitute w = 1 into 14w + 10:
14 + 10
=24
5. Substitute x = 2 into 2ײ-5×+6:
2×2²-5×2+6
2×4-5×2+6
8-5×2+6
8-10+6
-2+6
=4
6. ( Im sorry ? )
7. Substitute g = 3 into 16g - 42:
16 × 3 - 42
48 - 42
=6

Hope it helps!
