Question

If 6t-p=8 and 4t-3p=7, then t+p=

Answer 1

0.5.

Explanation:

1]. if to see the given equations as system, then:

`\left \{ {{6t-p=8} \atop {4t-3p=7}} \right. \ = > \ \left \{ {{(6t-p)-(4t-3p)=8-7} \atop {6t-p=8}} \right. \ = > \ \left \{ {{2t+2p=1} \atop {6t-p=8}} \right. \ = > \ \left \{ {{t+p=0.5} \atop {6t-p=8}} \right.`

2]. according to the item_1 t+p=0.5.
